The circuitry is configured such that when the power from the power source is absent, the switch is closed, and plural devices are connected on the supply side of the switch, the plurality of devices on the supply side appear as a substantially open circuit to the test signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for switch state detection and controlling electrical power","description":"A device includes a connection receiving power from a power source under normal conditions and circuitry configured to determine, based on an input from the connection, when the power from the power s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9608479","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
